Import Tips
• Include lab certification of natural rubber origin (e.g
• >50% NR content) to distinguish from synthetics
• Document that strips maintain rectangular cross-section without profile shaping for 4008 compliance
• Watch for reclassification if sold pre-cut for specific machinery as 'articles' under 4016
